Lefteris Karapetsas, founder of Rokti, joins the podcast. Lefteris has been around the Ethereum ecosystem since the beginning and we talk about his journey through crypto to date. He's contributed to Solidity, the C++ Ethereum client and helped mitigate the DAO attack. Since then he's worked with Raiden but has since moved on to building Rotki. We talk about Rotki's commitment to privacy and how it makes it very easy for anyone who deals with crypto to track their portfolio and ultimate turn it into a tax statement.
